Argyranthemum frutescens plant named &#39;argydowitis&#39;

ABSTRACT

A distinct cultivar of Marguerite Daisy plant named ‘Argydowitis’ characterized by its upright vigorous plant habit, good field performance, large semi-double white flowers, dark green colored leaves, freely flowering with numerous inflorescences per plant.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Argyranthemum frutescens

VARIETAL DENOMINATION

‘Argydowitis’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as Argyranthemum frutescens and referred to by the cultivar name ‘Argydowitis’. The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, The Netherlands. The objective of the breeding program was to develop a more vigorous plant that flowers early with a good field performance during the whole summer.

DESCRIPTION OF THE DRAWING

This new Marguerite Daisy plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures. The depicted plant is of the same age as disclosed in the botanical description.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Marguerite Daisy plant. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, The Netherlands. The plant history was taken on 20 weeks old plants, grown in the greenhouses in Enkhuizen, The Netherlands with day temperatures ranging from 12 to 18 degree C., and night temperatures ranging from 10 to 14 degrees Celsius. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London where general terms of ordinary dictionary significance are used.
